Smartphone Application for Mask Sizing and Projecting Quantitative Fit

Identifying the correct size of a full facepiece respirator for an individual requires a significant degree of skill. Furthermore, the fit assessment procedure is time consuming due to the series of tasks required to calculate the fit factor, a measure of the quality of fit. The Chemical and Biological Defense (CBD) program needs a quicker, less manually intensive, and more reliable method to select the correct respirators for individuals. In Phase I of this project, Technology Solutions Experts, Inc. (TSE) developed a proof-of-concept desktop application that, using 2D images of a subjects head as input, generated 3D headform models to match the shape of the subjects head. The proof-of-concept application analyzed the anthropometrics of this headform and then recommended the appropriate fit of Avon C50 respirator. In Phase II, TSE is proposing to develop the Mask Analysis and Size Quantification (MASQ) application, an extension of the technologies and methodologies TSE developed in Phase I. MASQ will analyze the subjects head using only 2D images as inputs and predict size and fit to within a 5% margin of error. Furthermore, MASQ will be deployed as a mobile application, enabling fit tests to occur at the point of need.
